soluti
on
HGWs (xDSL
upstream
transmission)
when MVLANs
on HGW side and
network side are
different:
l Upstream
IGMP
packets: The
extended
subrack
performs
IGMP proxy
to terminate
IGMP
packets
transmitted
from the user
side,
encapsulate
the packets
with an
MVLAN tag
on the
network side,
and send the
packets to the
extending
board.
l Downstream
multicast
service flows:
The extended
subrack
replicates
multicast
packets based
on user ports,
and
multicasts the
packets
among
MVLANs
(user VLAN
<- MVLAN).
l Upstream
IGMP
packets: The
master
subrack
performs
IGMP proxy
to terminate
IGMP
packets
transparently
transmitted
from the
extending
board and
reported by
the extended
subrack,
encapsulate
the packets
with an
MVLAN tag
on the
network side,
and send the
packets to the
upper-layer
network.
l Downstream
multicast
service flows:
The control
board in the
master
subrack
replicates
multicast
packets based
on Ethernet
extending
boards, and
the Ethernet
extending
boards
replicate
multicast
This solution is
recommended.
